MARKED UP VERSION OF THE AMENDED CLAIMS

1. (AMENDED)

Process for managing isochronous resources in a

communication network comprising at least two communication buses linked by way
of a wireless transmission bridge, the bridge comprising for each bus a real portal
connected to this bus, each portal being furnished with wireless communication
means, [characterized in that] wherein the process comprises the steps of:

modelling the wireless bridge by each real portal in the form of
virtual buses and virtual bridges, each virtual bridge comprising two virtual portals;

emulating a global register of passband availability for the set
of wireless links of the wireless bridge;

reserving passband with the global register for the virtual buses
representing each wireless link participating in a communication between two real
portals.

2. (AMENDED) . Process according to Claim 1, [characterized in that] wherein a
wireless link is modelled in the form of a virtual bridge.

3. (AMENDED) Process according to Claim 1, [characterized in that] wherein a
wireless link is modelled in the form of a virtual bus.

4. (AMENDED) Process according to Claim 1, [characterized in that] wherein a
group of wireless links linking a group of portals having complete connectivity within
a bigger network with partial connectivity is modelled in the form of a virtual bus.

5. (AMENDED) Process according to [one of Claims 3 or 4, characterized in
that] Claim 3, wherein each real portal emulates;

a virtual portal forming together with the real portal a bridge
linking the communication bus connected to the real portal to a virtual so-called
internal bus also emulated by the real portal;

a virtual bridge for each wireless link with another real portal.

6. (AMENDED) Process according to Claim 2, [characterized in that] wherein
each real portal emulates:

a virtual portal forming together with the real portal a bridge
linking the communication bus connected to the real portal to a virtual so-called
internal bus also emulated by the real portal;

a virtual portal for each wireless link with other portals of the
wireless bridge, two virtual portals corresponding to the same wireless link between
two real portals forming a virtual bridge representing the wireless link.

7. (AMENDED) Process according to [one of Claims 4 or 5, characterized in
that] Claim 4, wherein it furthermore comprises the step of eliminating an internal
bus and virtual portals connected thereto, and of contracting into a bridge the two
orphan portals thus created, in the case where the real portal comprising the internal
bus forms part of a single wireless link.

8. (AMENDED) Process according to [one of Claims 1 to 7, characterized in
that] Claim 1 , wherein it furthermore comprises the step of determining, by each real
portal, the set of wireless links between the real portals.

9. (AMENDED) Process according to. Claim 8, [characterized in that] wherein
the step of determining the set of wireless links comprises the steps of:

identifying, by each real portal, the other real portals whose

data reach it directly;

transmission destined for all the other real portals of the
wireless network, of the list of real portals with which a direct link exists;

reception of the list compiled by each of the other portals.

10. ( AMENDED) Process according to [one of the preceding claims,
characterized in that [ Claim 1 . wherein it also comprises the step of emulating a
register of availability of isochronous channels for each virtual bus.

1 1 .(AMENDED) Process according to [one of the preceding claims,
characterized in that] Claim 1 . wherein the step of reserving passband with the global
register comprises the instigating of a request for reserving passband with a manager
of isochronous resources of a virtual bus and for transmitting the request by the said
manager of isochronous resources of the virtual bus to a software module managing
the global register of passband availability.

12. (AMENDED) Process according to [one of Claims 1 to 1 1, characterized in
that] Claim 1 . wherein the bridge comprises at least three portals.
